Gautam Kumar Parai updated CALCITE-2366:
----------------------------------------
    Description: 
We had discussions on the Apache Calcite [1] and Apache Drill [2] mailing lists 
regarding an equivalent for DISTINCT ON. The community seems to prefer the 
ANY_VALUE. This Jira is a placeholder for implementing the ANY_VALUE aggregate 
function in Apache Calcite.
